SHEET-INSERTER.

No. 923,325. Specification of Letters Patent. Patented June 1, 1909.

To all whom it may concern:

Be it known that I, Jon; L. BROWN, citizen of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in Sheet- Inserters; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art i to which it appertains to make and use the same.

This invention relates to improvements in loose leaf inserters.

The object of the invention is to provide a device of this character by means of which loose leaves may be quickly and easily inserted in loose leaf ledger or other forms of loose leaf binders, having either rigid or telescoping binding posts.

\Vith the foregoing and. other objects in view, the invention consists of certain novel features of construction, combination and arrangement of parts, as will be more fully described and particularly pointed out in the appended claims.

I11 the accompanying drawings, Figure 1 is a plan view of an inserter showing the loose leaf arranged therein; Fig. is a 1011- gitudinal sectional view of the same; Fig. 3 is a plan view on an enlarged scale of one end of the upper section or plate of the inserter, parts of the same being shown in section; Fig. t is a similar view showing the manner in which the springs on the plate operate in passing the binding posts of the ledger; Fig. 5 is a perspective view of the lower plate or section of the inserter.

Referring more particularly to the draw ings, 1 denotes the inserter which consists of an upper plate or member 2 and a lower plate or member 3. In the inner edges of the members 2 and 3, adjacent to each end, are formed notches f and between said notches 4 are formed centrally disposed notches Around the notches 4 on the upper side of the top plate or member 2 are formed flanges 6 in which, adjacent to the inner edge of the plate or member 2, are formed slots or passages 7. Secured to the upper side of the top plate, opposite each of the flanged notches 4, are bowed springs 8, said springs being secured to the plate at their inner or looped ends by soldering or other suitable fastening means. The free ends of the springs are bent to form right-angular inwardly projecting fingers 9 which project through the slots or passages T in the flange 6. The inner ends of the lingers 9 project across the outer ends of the notches I for a purpose hereinafter described.

(in the opposite ends of the lower plate or member of the inserter are formed upwardly projecting flanges 10, the upper edges of which are beveled or inclined toward the inner edge of the plate, as is clearly shown in Fig. 5 of the drawings. The flanges 10 are provided to hold the leaf and the upper plate or member in position on the lower plate or member so that the notches in the plates and in the leaf will be maintained in perfect alinel'nent.

In the operation of the device, the inner end of the leaf to be inserted is arranged between the upper and lower plates or members 2 and 3, the inner edge of the leaf being arranged flush with the inner edges of the inserter plates with the notches in the leaf coinciding with the notches in the plates. When the leaf has been thus engaged with the plates, the latter are grasped at their opposite ends and held together after which the plates together with the leaf are inserted atthe desired position in the ledger. The plates and the end of the leaf are pushed or forced inwardly until the notches in the plates and leaf have engaged the binding posts of the ledger after which the upper plate or member 2 is withdrawn. The inserted leaf is now laid against those already in the ledger by tilting the lower plate or member 3 back against the leaves after which the plate or member 2 is withdrawn, leaving the inserted leaf in position.

When the leaf is being inserted, as hereinbefore described, the binding posts of the ledger will force the spring fingers back through the slots in the flanges 6, thus permitting the leaf retaining projections or points at the inner ends of the notches or cut-out portions of the leaf to bend upwardly in passing the posts. After the spring fingers have been thus pushed by the posts, they will again spring outwardly and in so doing will smooth the projections or points of the ledger leaf down in operative position, behind the posts to retain the sheet in place. In withdrawing the upper plate or member, the spring fingers will be forced back to allow the notches in the plate 2 to be disengaged from the posts.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details of construction may be resorted to Without departing from the principle or sacrificing any of the advantages of the invention, as defined in the appended claims.

Having thus described my inventi0n,what I claim is:

1. In a loose leaf inserter, upper and lower sheet holding plates having formed therein post engaging notches to correspond with the post engaging notches in the leaf, means to hold the plates in operative engagement with the leaf, and means whereby the retaining devices on the ledger leaf are restored to an operative position, after passing the binding posts of the ledger.

2. A loose leaf inserter comprising upper and lower sheet holding plates having formed therein alined post engaging notches adapted to coincide with the sheet retaining notches in the sheet, slotted flanges arranged around the edges of the recesses in said upper plate, springs arranged on the outer side 1 of said upper plate, and fingers formed on the ends of said springs to Work through slots in the flanges of the notches in said plate whereby the retaining devices in the post engaging notches are smoothed out or restored to operative positions after being forced by the binding posts in the insertion of the sheet.

A loose leaf inserter comprising upper and lower sheet engaging plates having formed in their inner edges alined post engaging notches, inclined flanges formed on the opposite ends of the lower plate whereby the upper plate and sheet are held in operative position with the post engaging notches therein in alinement, and means on the upper sheet holding plate to restore the retaining devices of the sheet to their normal or operative position after being forced by the binding posts of the ledger.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
